七叶莲不同醇沉工艺评价

Evaluation of Different Ethanol Precipitation Process about Schefflera arboricola Hayata

目的考察不同醇沉方式对七叶莲醇沉产物品质的影响。方法七叶莲水提液分别采用50%,60%,70%,80%4个浓度按计算量一次醇沉、分次醇沉、分级醇沉、多次醇沉4种不同工艺制备醇沉产物,采用聚类分析的方法对不同醇沉产物的品质进行综合评价。结果 16种样品以浓度为依据聚类,在各自浓度下醇沉工艺不同聚合距离不同。结论醇沉浓度对醇沉效果影响较大,醇沉工艺对醇沉效果有一定的影响。

Objective Compared the ethanol precipitated products＇ quality about Schefflera arboricola Hayata by different ways of ethanol precipitation. Methods Four different processes were carried out with ethanol concentration 50%,60%,70%,80%,and evalued the quality of different products by cluster analysis. Results Samples were clustered based on the concentration,and they were different with different process. Conclution Ethanol concentration has a greater influence on the products,meanwhile ethanol precipitation process has some influence.
